In addition to maintenance, don't forget about upgrades, newer versions and installation/maintenance of those. Early on in the food making robot game it will move fast, new versions will come out all the time. Noone wants to eat at the place with last year's robots. Early on, competing will be intense if the new versions also cut costs heavily. No restaurant that has gone automation will be able to survive if using too far outdated robots in the beginning at least, until it is refined after many iterations. Humans are self-cleaning and maintain on their own time. Robots will be like any other kitchen equipment, probably very nasty unless there are humans there to clean them on the regular, good policies or really good self-cleaning technology. Eventually there will be robot upgrading and maintaining third party services, but at that point are you really getting a difference across restaurants other than ingredients? Sometimes people like chefs cooking because it is unique and harder to replicate. We already get lots of food made by robots, they are frozen foods that aren't all that great compared to food made on the spot by real people.
